WVILLIAM HOSMER, OF

AUBURN, NEW YORK.

IMPROVED COOK-STOVE.

Specification forming part of Letters Patent No. 44,424, dated September 27, 1864.

To all whom it may concern:

Be it known that 1, WILLIAM HOSHER, of Auburn, in the county of Cayuga and State of New York, have invented a new and useful Improvement in Cook-Stoves; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the ac-. c mpanying drawings, forming part of this specification, in which Figure l is a longitudinal vertical section of my invention taken in the line a0 :10, Fig. 2; Fig. 2, a horizontal section of the same taken in the line ;1 3 Fig. l.

Simiiar letters of reference indicate corresponding parts.

Th s invention relates to a new and useful object economy in the use of fuel. This object is efl'ected by two different means. First,by a novel construction and arrangement of the firechamber, whereby the same may be expanded or contracted at will; and, second, in a novel arrangement of flues whereby a sinuous draft is obtained when desired, and consequently a greater radiation of heat.

The cook-stove may be construct-ed in the usual form, A being the fire-chamber, and B the flue leading from the same. At the sides of the fire-chamber, front and back, and at the ends, there are shoulders a, on which horizon tal plates 0 0 rest. The plate G is allowed to slide over the other one, C, and the former is provided with a pendent plate, D which projects downinto the fire-chamber, and is equal in area to one end of the same.

By moving the plate 0 it will be seen that the capacity of the tirechamber may be increased or diminished, as desired, from onehalf to a less capacity, and at any time, if the whole of the fire-chamber is required, both plates 0 C may be removed. By this arrangement it will also be seen that a great saving in fuel will be effected, for there are many cases in which a moderate fire is only required, and if the fire-chamber cannot be contracted, as is the case with the ordina-rystoves, an unnecessary amount of fuel will be consumed.

The flue B is provided with a series of damp ers, D, which are placed transversely in it, and are equal in width to the height of said flue, so as to extend, when raised, from its bottom to its top. ,Each damper is a trifle shorter than the width of the flue, so as to leave a space or opening, a, at their ends, the openings of the dampers consecutively being at opposite sides of the flue, as shown clearly in Fig. 2. These dampers have rods 1) extending through one side of the stove, with bent or crank ends a, by which the dampers may be turned or adjusted. When the dampers are raised, it will be seen thata serpentine or sinuous passage is formed in the flue B for the products of combustion to pass through, and consequently a greater radiation of heat will be obtained than if the flue B were entirely open or unobstructed. The sinuous dratt-passage also gives efliciency to a small fire, and is a necessary or very advantageous feature when used in connection with the contracted fire-chamber. When the platesO C are removed from the fire-chamber, the dampers D may be turned down, so as to leave the flue B unobstructed.

I claim as new and desire to secure by Letters Patent 1. The plates 0 G, fitted within the firechamber, and arranged substantially as shown, for the purpose specified.

2. The employment or use of a series of dampers, D, placed within the flue B, and arranged substantially as and for the purpose set forth.

3. The combination of the dampers D in the flue B with the plates 0 U in the fire-chamber, as and for the purpose specified.
